Built for 400GbE Enterprise Data Centre Fabrics
The NVIDIA SN5400 is designed for high-performance Ethernet environments where 400GbE switching is required across AI, storage, cloud and enterprise data centre networks. With 64 QSFP56-DD ports, this switch is well suited to dense spine, aggregation and high-speed fabric designs.
The 920-9N42C-00FB-7C0 provides the same 400GbE Spectrum-4 switching platform as the C2P airflow version, but with power-to-connector airflow for racks and data centre environments that require the opposite cooling direction.
